The foods filling most American shopping carts and dinner tables are literally killing us, according to mounting scientific evidence.
Story Overview
- Ultra-processed foods now comprise 70% of packaged foods in America, with children getting over 60% of their calories from these products
- Harvard researchers link specific ultra-processed foods to increased early death rates, particularly processed meats and sugary beverages
- Federal agencies HHS, FDA, and USDA officially acknowledge ultra-processed foods as a major public health threat requiring urgent action
- NIH clinical trials prove causality between ultra-processed food consumption and weight gain, moving beyond correlation to direct evidence
- Low-income communities face disproportionate health risks due to greater reliance on affordable ultra-processed options
The Scientific Evidence Reaches Critical Mass
Harvard researchers delivered a devastating blow to the ultra-processed food industry with their 2024 study published in The BMJ. The research tracked over 100,000 health professionals for three decades and found that people consuming the highest amounts of ultra-processed foods faced significantly increased risks of early death. Dr. Mingyang Song, the lead researcher, discovered that processed meats, sugary drinks, and certain breakfast foods posed the greatest dangers, while some ultra-processed items like whole grain breads showed less harmful effects.
Watch:
Federal Agencies Break Their Silence
The Department of Health and Human Services, FDA, and USDA issued an unprecedented joint statement in July 2025 acknowledging that ultra-processed foods pose serious health risks requiring immediate attention. This marked the first time these powerful agencies collectively admitted that the American food system actively harms public health. Their statement emphasized that addressing ultra-processed food overconsumption has become a cornerstone of national health strategy.
The agencies’ admission carries enormous weight because federal health officials rarely make such definitive statements about specific food categories. Their willingness to potentially antagonize the powerful food industry lobby signals that the scientific evidence has become too overwhelming to ignore.

The Smoking Gun From NIH Clinical Trials
The National Institutes of Health provided the smoking gun evidence that transformed this from a correlation debate into proven causation. Dr. Kevin Hall’s groundbreaking 2019 randomized controlled trial housed participants in a clinical center for four weeks, feeding one group ultra-processed foods and another group unprocessed foods with identical calories, sugar, fat, fiber, and macronutrients.
The results stunned the scientific community. Participants eating ultra-processed foods consumed an average of 500 more calories per day and gained two pounds, while the unprocessed food group lost two pounds. This clinical trial eliminated every possible confounding variable and proved that ultra-processed foods directly cause overeating and weight gain through mechanisms still being investigated.
The Disproportionate Impact on Vulnerable Communities
The American Medical Association warns that ultra-processed foods create a two-tiered health system where economic status determines disease risk. Low-income families depend heavily on ultra-processed foods because they cost less, last longer, and require minimal preparation time. Dr. Devries from the AMA describes the health consequences as “dire,” linking ultra-processed food consumption to more than 30 health conditions including cardiovascular disease, type 2 diabetes, and various cancers. This creates a vicious cycle where communities with the least access to healthcare face the highest exposure to foods that cause chronic diseases.
